To all whom it may concern:

Be it known that we, CHARLES A. PAIN- Tnn, J r., and James P. MCKINNEY,Jr, citizens of the United States, and residents of Pittsburgh, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Door-Locks; and we do hereby declare the followingto be a full, clear, and exact description thereof.

Our invention relates to latches for doors of automobiles, or for otherpurposes to which it may be found applicable.

The object of the invention is to provide a simple and eflicient form oflatch in which the thumb-piece or handle is in such position that itdoes not project beyond the door wall where it would be in position tobe struck by an object or catch on the clothing of a person entering orleaving the car; and, at the same time, giving a neater and moreattractive appearance. v

Referring to the accompanying drawing, Figure l is an inside view of adoor of an automobile with the panel partly broken away to show theparts of the latch; Fig. 2 is a section on the line 22, Fig. 1; and Fig.8 is a section on the line 3-3, Fig. 1.

In the drawing, the numeral 2 designates an automobile door or anysuitable construction, said door being formed with the depression orrecess 3 adjacent to the upperrim 4 of the door. Secured to the doorwithin said depression is the guide-plate 5, which is held in positionby screws 6 or other suitable fastening devices. This guide-plate 5 hasthe slot 7 which acts as a guide for the vertically movable strap 8.Secured to the vertically movable strap 8 isthe thumbpiece comprising aT-shaped member with the flange like crosspiece 9 with the downwardlyprojecting tail piece 10, by means of which said thumb-piece is securedto said vertically movable strap 8. Screws 11 or other suitablefastening devices may be used for this purpose. The downwardly extendingportion 10 fits within the slot 7 of the Specification of LettersPatent.

guide-plate and is adapted to move up and down therein as thethumb-piece is raised or lowered.

In this manner the thumb-piece is located within the recess 3, and doesnot project beyond the do0r-panel so that it does not form anobstruction of any kind, which may be struck by any object or catch uponthe clothing. Being located adjacent to the top edge at of the door, tolift the thumb-piece the fingers of the hand may rest upon the edge l,while the thumb engages the thumbpiece and in this way the necessaryleverage is obtained to readily move the thumbpiece up to release thelatch.

The vertically movable strap 8 has the slot 12 which engages the pin 13on the plate lat. Pivotally secured to the lower end of the verticallymovable member 8 is the toggle-arm 15, which has a pin 16 engaging theinner end 17 of the bolt 18. A stud 19 acts as a stop for the verticallymovable member when said member is raised, and thetoggle-arm l5 acts tothrow I scription that upon lifting the thumb-piece 9, the verticallymovable strap 8 will be raised and the toggle-arm 15 moved to theposition indicated in dotted lines, Fig. 1, and the bolt will be thrownback to disengage the latch. The thumb-piece 9 is raised by a directvertical pressure, and being guided within the slot 7 the movement ofthe thumb-piece is the same at whatever point the pressure is applied tolift the same.

WVhat we claim is:

The combination of a door having a recess formed in its wall adjacent tothe upper edge of the door, a guide-plate in said recess having avertical. slot, a T-shaped thumb piece comprising a flangelikecrosspiece, and a tail piece, said tail-piece having a sliding fit withsaid slot, a vertically-movable strap, said tail-piece resting inengagement with said strap and secured thereto, a A. PAINTER, J1'., andJAMES P. MCKINNEY, bolt, and connections between said bolt and J r.,have hereunto set our hands.

said vertioa1ly-movab1e strap whereby the CHARLES A PAINTER JR operatorwith his hand on the upper ed e of V the door and the thumb engagingsaid c ioss- JAMES MCKINNEY piece, obtains the purchase for raising saidWitnesses: vertically-movable strap to release the bolt.
